  1. Gary says:

    I don’t have a water heater in my campervan, so do the comments about the use of Milton-type fluids still apply. I have never used this before, but would consider it as long as it caused no problems for my pump or fittings.

  2. David Daniel says:

    Could a solution of white vinegar be used to clean water pipes and tanks?

  3. Terry Stevenson says:

    All this about sterilizer agents is fine but how do I introduce it into my fw tank when I have a Whale connection with an inbuilt circuit to a fill solenoid. I know of no other way to get it in unless I manufacture a pressure vessel on the fresh water supply hose pipe. With in and outlet connections. Full the vessel with steriliser, then the fill water will flush it through to the tank.

  4. lorraine curtis says:

    Despite you saying you have ammended the article it still has Milton listed as suitable, good job I read further down. Lots of other good tips though.

  5. Jay says:

    Can bicarbonate of soda be used to clean the whole system and not just the aqua roll, or would that effect the heater ?

    • Liz @ Caravan Guard says:

      Bicarbonate will clean but it won’t sterilise. Make sure any water filter is removed though.

  6. ROGER BANKS says:

    I bet you are really glad that you mentioned “Milton”in you article…..

    • Liz @ Caravan Guard says:

      It’s been removed now Roger – but we like to get it right so thanks for your comments.

  7. john keegan says:

  8. ROGER BANKS says:

    Thanks Liz.,not 100% up to speed with computers,I thought I had to press another button to send comment.

  9. ROGER BANKS says:

    What does “your comment is awaiting moderation” mean ?

  10. ROGER BANKS says:

    Dont use MILTON,it can damage your water pump seals according to instructions.

    • Liz @ Caravan Guard says:

      Thanks Roger. We’ve amended the article to take out the reference to Milton and are waiting for more information from Truma.

  11. Sandra says:

    First time caravanners and just brought out storage and never thought of sterilising water tanks

  12. Paul trenfield says:

    All very good tips and work well.

  13. Peter Cleanpipe says:

    Probably the best cleaning suggestions I have ever read

  14. Fred says:

    I always use aquatabs in the hog to sterilize my system I the spring! Same result

  15. Bill Bowmar says:

    When ever I leave a site, I put Milton into my Aquaroll, pump it through all pipes until I can smell the chlorine. On arrival at the next site (or my storage location) I drain down the system and leave the dregs in the Aquaroll until the next trip.

    To avoid tummy troubles we always use bottled water for hot and cold drinks, keeping a two litre bottle in the fridge for cold drinks.

  16. Kevin says:

    I would like to see a twin wheel caravan. with a maximum payload of 1500kg. Twin wheeler and a central washroom.

  17. Rob Hayes says:

    Hi to all. Been using sterilising fluid through my system for a long time, a couple of cap fulls per 14 pints of water into your aqua roll let it stand then move the roll around in a rinse out motion, put the pump into the roll put it through your caravan system with the outlets closed, this will treat the smells a little in the waste pipes, next day flush the system with clean water, do this a couple of times to make sure that the tap water taste is fine otherwise your tea and coffee isn’t very nice, put fresh water through the system until you are happy.

  18. Sally Newton says:

    Thanks for that warning, I was just about to use Milton, so will not now. I have flushed the system through with fresh water, so will leave it at that. We don’t drink it uncoiled anyway. Would I be ok soaking the Whale unit in the Milton or best just to use white vinegar?

    • Liz @ Caravan Guard says:

      We’ve contacted Whale pumps and they say Milton can react with stainless steel, however it depends on the grade of steel and the concentration of the solution. If left in a stainless steel sink it can cause a staining of the metal. The “WH” heaters are cast aluminium with a surface treatment (Teflon style coating). These should be okay as the solution will not come into contact with the tank material.
      Vinegar can be used in the water system but this will not kill germs. Vinegar, if flushed through the water heater will only remove lime scale from metal surfaces that it has built up on. Normally the heating element.
      Puriclean seems to be a popular choice. Hope this helps?

    New to this site. Great tips

  21. Bert Cleanpipe says:

    Perfect probably the best article I have ever read

  22. Robert Hayes says:

    Thanks for the tips

  23. Martin says:

    Can you confirm Milton is safe to use in Truma combi boilers? I seem to recall reading somewhere that it could cause premature failure of the tank. Always used Milton in the aquarolls though with great success.

    • Liz @ Caravan Guard says:

      We’ve contacted Truma for their advice and will update when we hear back. In the meantime we’ve taken out the reference to Milton.

    • Liz @ Caravan Guard says:

      Hi Martin, we’ve contacted Truma and they don’t recommend the use of Milton because if it is left for too long it can cause damage to the water tank. They don’t recommend a particular product and advise people to speak to their dealer to see what they stock and recommend.

  24. Brian Hankins says:

    Do NOT use Milton or any kind of bleach related product in your water tank, the experts say that it is not good for the water heater and avoid at all costs. The best product for cleaning your water system is white vinegar one to two litres per 100ltr tank should do it. Leave over night and then flush through with clean water, may take one or two flushes. Got this tip from Diamond Dave, Practical Motorhome Channel.

    • Liz @ Caravan Guard says:

      Thanks for your tip Brian. We’ve amended the article to take out the reference to Milton.
